General Issues: | General Issues: | ||
+ | - Calendar didn't include Hobart even though it was on the master schedule. The 26m was a late addition to the AUA schedule. Should be avoided in future. | ||
+ | - Let Jamie know if you don't have access rights to the calendar. | ||
+ | - nobs looks at master schedule. Warren's script already checks master schedule. | ||
+ | - CHECK THE MASTER SCHEDULE! and the start time. | ||
+ | - Jesse sent around an email about script. Works for ho, hb, ke and yg, and opens most of the windows needed. | ||
+ | - didn't put delay plots in the right position; this is because they were already open. | ||
+ | - run windex before windows if there is stuff open. | ||

- Ho: iread power levels are a bit low 28000 and 38000 of 48000 | changing attentuation did nothing to help (OHG109) | - Ho: iread power levels are a bit low 28000 and 38000 of 48000 | changing attentuation did nothing to help (OHG109) | ||
+ | - mot an issue: got a different frequency range for O'Higgins (uses Mark 4 rack), slightly smaller range, different power and temperatures. Not paying attention to read in this experiment. Needs more tests. | ||
+ | - Tsys temperatures below 200 now seem okay, probably degradation of the system. Measured wrong due to absolute calibration error but maybe 10-20% due to the degradation. | ||
+ | - Ho: problems with cryo temp (OHG109 and AUA031) | ||
+ | - Just summer maybe. Also receiver pressure a bit dodgy, at 4 microns. Build of gases, got over 5 microns last night but was pumped down. Summer season so cryo problems likely to be more of an issue. Keep an eye out. | ||
- Ke: Ran fivept several times, the offsets are looking a bit dodgy (AUA031) | - Ke: Ran fivept several times, the offsets are looking a bit dodgy (AUA031) | ||
+ | - Problem after bad storms in Katherine. Bryn could get below 0.04 offset even after several attempts. Jamie to work on this. | ||
+ | - Similarly, fringe testing is quite rubbish these days. | ||
- Yg: alarms going off for illegal state error and unable to read systemclock1. antenna=open antenna=operate fixed the issue (R1816) | - Yg: alarms going off for illegal state error and unable to read systemclock1. antenna=open antenna=operate fixed the issue (R1816) | ||
+ | - Bryn breaks stuff. This issue has come up for both Tiege and Liz too. HMI clock get confused about the time; need to reset if the simple fix fails. |
